Indeed, wish they released it as separate DAC and an amp. DAC components usually get outdated really fast while amplifiers last for a very long time.
Here are pictures I took.
I like design. It is solid-state (no tubes found!) with enough juice to drive both orthos and high-impedance headphones.
It has variable output impedances, a bit vaguely saying "8~40", "40~150" and "150~300". I am not sure whether it has enough damping factor to drive Audezes, but sure it did drive HD600 (which was also a demo unit besides T50RP)
Only problem, like other McIntosh products, is price. No way I am going to pay 5K for just a single-ended-only headphone amplifier.
